Description

User equipment, method and device in base station used for wireless communication

Technical field

The present invention relates to a transmission method and apparatus in wireless communication, and more particularly to a method and apparatus for communication between an air terminal and a ground device.

Background technique

In the 3GPP (3rd Generation Partner Project) Release 12, D2D (Device to Device) communication is proposed and discussed. The essential feature of D2D is that it allows the user equipment (User Equipment). Data transfer between. In traditional D2D communication, considering the robustness of D2D transmission and interference to Cellular communication, when the D2D UE is located under the coverage of the cellular network, the D2D UE is on the Sidelink. And the transmission on the cellular link is controlled by a serving cell corresponding to the D2D user equipment.

In the 3GPP discussion on 5G, SI (Study Item) on Enhanced Support for Aerial Vehicles has been established and discussed in 3GPP. One feature of over-the-air communication is that the transmission of an air terminal device is detected by multiple base stations, and the corresponding transmission method between the air terminal and the ground terminal needs to be reconsidered.

Summary of the invention

An important feature of air communication is that the terminal located in the air is often LOS (Line of Sight) between the ground terminal and the base station after reaching a certain height. Because of the LOS path, when the air terminal in the target cell communicates with the ground terminal corresponding to the air terminal or the base station corresponding to the target cell, the ground terminal and the neighboring cell of the neighboring cell in the vicinity of the target cell The corresponding base stations can receive signals from the air terminals, thereby causing large inter-cell interference.

In the existing LTE (Long Term Evolution) D2D application scenario, the transmission of the D2D transmitting end is based on the control of the serving cell of the transmitting end, whether the receiving object is the base station or the receiving object is the peer user equipment of the D2D transmitting end. The above method is to ensure The transmission at the D2D sender does not cause interference to the cellular link. The communication between the air terminal and the terrestrial terminal in over-the-air communication will largely inherit the transmission protocol of LTE D2D communication. At the same time, in the discussion of Release 2 based on D2D V2X (Vehicle to X) evolution, GNSS (Global Navigation Satellite System) synchronization is also introduced into the synchronization application between D2D pairs. The transmission of the air terminal can be received by the base station corresponding to the plurality of cells on the ground, and the air terminal is more easily synchronized with the GNSS. The new air terminal-based transmission mode needs to be considered.

In response to the above problems, the present invention provides a solution. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments of the present application may be combined with each other arbitrarily. For example, features in embodiments and embodiments in the user equipment of the present application may be applied to a base station, and vice versa.

As an embodiment, the above method has the advantage that since the LOS path is between the ground station or the terminal, the air terminal simultaneously communicates with two ground devices, one of which is used for synchronization, and the other ground device is Used to transmit control information. The above method makes the transmission of the air terminal and the ground terminal more flexible, and does not need to transmit all the information of the air terminal through the serving cell, thereby avoiding the problem of frequent switching of the air terminal.

As an embodiment, another feature of the above method is: existing V2X design, when The synchronization source of the D2D device is a GNSS, and the SLSSID (Sidelink Synchronization Sequence Identifier) used by the D2D device to generate a signature sequence of the synchronization sequence is fixed. In the above method, the first sequence of features is configurable when the third wireless signal is synchronized by a peer device for the airborne device and the second wireless signal is a signal from a GNSS. The above method increases the flexibility of the system, which makes it easier to distinguish synchronization signals from different airborne devices.

As an embodiment, another feature of the foregoing method is: when the third wireless signal is used for at least one of { transmit power control, triggering the user equipment to send a reference signal, triggering the user equipment to send channel state information}. At one time, the sending of the third wireless signal is triggered based on a cell other than the sender of the first wireless signal and the sender of the second wireless signal, thereby implementing an air terminal when the air terminal moves out of the serving cell Any cell in the coverage supports the transmission of non-scheduled control signaling to the air terminal, further improving the mobility of the air terminal and increasing the flexibility of the system.

In the existing V2X design, when the synchronization source of the D2D device is a GNSS, the SLSSID of the feature sequence used by the D2D device to generate the synchronization sequence is fixed. In the method, the first sequence of features is configurable when the third wireless signal is synchronized by a peer device for the airborne device and the second wireless signal is a signal from a GNSS.
